Texas Integrated Flooding Framework

Coastal flood events result in billions of dollars in damage to coastal infrastructure.

For Texas to implement State and Regional Flood Planning, decision-makers need a more accurate understanding of coastal flood risks and the tools for effective mitigation planning.

Texas Integrated Flooding Framework (TIFF)

Over the next four years, TIFF, led by the Texas Water Development Board, U.S. Army Corps of Engineers, and U.S. Geological Survey, will develop the guidelines and processes for implementing an integrated framework to model, visualize, and plan for the risk of flooding in counties affected by Hurricane Harvey.

TIFF components will compliment the many ongoing efforts to enhance flood science, mapping, modeling, warning, response, and planning in Texas.

What is Compound Flooding?

The most common type of compound flooding is a combination of storm surge and riverine flooding that can produce floodwaters longer in duration and more spatially extensive than anticipated.

The Intergovernmental Panel on Climate Change (IPCC, 2012) defines compound flooding as

  • Two or more extreme events occurring simultaneously or successively.
  • Combinations of extreme events with underlying conditions that amplify the impact of the events.
  • Combinations of events that are not themselves extremes but lead to an extreme event or impact when combined.

TIFF Components

Four primary components will be done in parallel, in collaboration with each other, and through an iterative process, with the help of technical advisory teams.

Technical Advisory Teams

Each component has a technical advisory team made up of experts from Texas and the U.S. Team members serve on the component team aligned with their expertise. Team membership is voluntary.

Initial invitees were chosen by the Steering Committee; however, if an invitee could not participate, they could nominate someone to fill the space. Approximately 100 invitations were sent to potential technical advisory team members.

An example of the expertise needed for the component 1 technical advisory team is shown in the technical advisory team example graphic.
